Profile of a blast furnace and its dimensions are adapted to technology of process, see Figure. The bottom cylindrical part of the profile is called a hearth, wherein pig iron and slag are accumulated and periodically discharged through tap holes. Tuyeres through which hot wind and additional fuels are blown extend into the upper part of a hearth.

blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").
The electric arc furnace uses primarily electrical energy to supply heat to melt scrap steel, sponge iron, or mixtures of scrap and other iron units. Compared to the BOS process, the EAF requires less chemical reaction for refining. Shaping & Coating The liquid steel can then be cast or formed into a variety of solid shapes via the 'continuous ...
The electric arc furnace consists of a circular bath with a movable roof, through which three graphite electrodes can be raised or lowered. At the start of the process, the electrodes are withdrawn and the roof swung clear. The steel scrap is then charged into the furnace from a large steel basket lowered from an overhead travelling crane.
